How did master thomas respond when douglas asked for protection from covey?

"Master Thomas ridiculed the idea that there was any danger of Mr. Covey’s killing me, and said that he knew Mr. Covey; that he was a good man, and that he could not think of taking me from him; that, should he do so, he would lose the whole year’s wages; that I belonged to Mr. Covey for one year, and that I must go back to him, come what might; and that I must not trouble him with any more stories, or that he would himself get hold of me."
